Abstract: 1. A method for exterminating pest animals, wherein they are exterminated by electric influence, as by means of an enticement the pest animal is guided to a space limited by two electrodes, one of which it is forced to touch following its way to the enticement characterized in that the pest animal is in touch with one of the electrodes while walking over it and depending on the weight of the pest animal, and the value of the tension necessary to produce discharges into the space limited by the two electrodes is determined, the discharges exterminate the pest animal, the animal is guided through the space between the two electrodes by making it climb to a determined height, the tension between the two electrodes is supplied after the pest animal has entered deeply in the space between the electrodes, the carcass of the exterminated pest animal is removed from the space between the electrodes by slipping down by its gravity to the corresponding place for carcass collection, and after this the tension between the electrodes is switched off and the device remains in stand by mode awaiting the next cycle of pest animal extermination. 2. A method according to claim 1 characterized in that the tension is supplied constantly between the lower electrode and the middle of the upper electrode, supplying the tension to both terminals of the upper electrode immediately after the pest animal enters the zone under the middle part of the upper electrode. 3. A method according to claim 1 characterized in that the value of the tension range supplied to both electrodes has a value, securing the extermination of crawling pest animals of a determined type-size. 4. A method according to claims 1 and 3 characterized in that the constant tension range value supplied to both electrodes secures the extermination of pest animals in the instant when the pest animal rises to reach the enticement. 5. A device for exterminating pest animals, consisting of a passage with an electrode placed above its floor connected to a switch that is connected to the phase of a high tension source, the floor, being fixed on springs arranged under it and an enticement, is located in the passage characterized in that the passage (1) is inclined and is placed on a rack (8), being the enticement (6) placed in its lower end, and the floor is a second electrode (7) connected with a pin (9) to the runner of a rheostat (10) connected to the zero lead of the high tension source (4), the springs (5) being arch-shaped sheets, wherein to the upper clear of the passage (1) is positioned a replaceable chute (11) with a section according to the size of the largest animals to be exterminated, and under the lower clear of the passage (1) is positioned a second chute (12) to a container (13), in an orifice in the floor being placed a light emitter (14), and a light indicator (15) above it, its lead being connected to the first control input of the switch (3) and to the control input of a timer (15'), its output being connected to the second control input of the switch (3). 6. A device for exterminating pest animals according to claim 5 characterized in that the upper electrode (2) is divided by insulators (16) in three parts, the middle part (i7) being connected to the phase of the high tension source (4), and both terminals (18) are connected to the switch (3), wherein the light indicator (15) is located in one of the side walls of the passage (1) just after the boundary between- the higher part (18) and the middle part (17), and the lower electrode (7) is monolithic. 7. A device for exterminating pest animals according to claim 5 characterized in that the lower electrode (7) is stationary and is directly connected to the zero lead of the high tension source (4), the upper electrode (2) being directly connected to its phase lead, and both electrodes (2, 7) being monolithic. 8. A device for exterminating pest animals according to claims 5 and 7 characterized in that the lower electrode (7) has an orifice (19) positioned above the second chute (12), the first chute (11) being located to the lower part of the lower electrode (7), the passage (1) having a bottom (20) in its higher part, and the enticement (6) being placed at a height h on the inner wall of the bottom (20). 9. A device for exterminating pest animals according to claims 5, 7 and 8 characterized in that the container (13) is a pit in the earth, the second electrode (7) being an inclined plane to the pitfall with moistened soil, ending with a natural vertical surface that is the bottom (20), and under the first electrode (2) is located a trigger (21) with the enticement which is a bait (6), the trigger (21) being connected to the control inputs of the switch (3) and the timer (15'), wherein in the place beneath the trigger (21), in the soil, there is a heater (22), connected through a threshold switch (23) to an energy supply source (24), and a temperature indicator (25) in the soil is connected to a control input of the threshold switch (23). 10. A device for exterminating pest animals according to claims 5 and 6 characterized in that a groove (26) is made in the upper part of the lower electrode (7), and between the groove (26) and the chute (11) there is an elevated plain platform (27), and to the upper end of the upper electrode (7) there is an insulation extension (28).
